Manufacturing Process
1. Drawing & Cutting
Tested raw materials are drawn to desired diameter using wire drawing machines, then cut into rod-shaped punching pin blanks of fixed length.
2. Heat Treatment
Punching blanks are straightened on a straightening platform with dial gauge, then heated to 800-1300°C for 2-5 minutes in high-frequency electric or salt bath furnaces. After oil quenching and hardening, tip hardness reaches Hv590-800, followed by low temperature tempering treatment.
3. Grinding Processing
Punching pins are clamped on machine tool spring collets, with grinding forming processes performed according to angular requirements of various needle bases.
4. Polishing
Surface cleaning to remove oil, rust, and other contaminants for a clean finish.
5. Inspection & Storage
Comprehensive inspection against required specifications, with qualified products packaged and stored in warehouse.
